Xiaomi Air Purifier 2S - Filter Replace(Not Original)

One year later my Xiaomi Air Purifier 2S is asking to replace the filter.
I got a non original one and it works, but I believe the life span is smaller.

Thanks. I thought the machine will not work without the original filter.

Do you recommend? As it’s hard to buy original 1 from eBay / Amazon/ Ali express

Thanks. Valuable info that it is functional with non RF filter in.
What if you put the new fake filter with old RFID sticker? Is it measures a real air purity to estimate state of filter or just measures working time?
A yeah saw below you broke the sticker...

based on your video, i put a very thin metal plate under the NFC reader and now i can re-use the filter again and again until i see reduction in the air quality.

does it still work with 0% filter life

[EricTheTechGuy]

I have chinese version and getting 0% during boot up then the rest are chinese. I assume the filter requires reaaplcement. Please confirm if the % during the initial boot is the filter life.
